If I remember correctly there is a point at which you can see both Plum Island and Orient Point from - I don't mean you can see both at the same time, though.

I mean if you are walking along the shoreline and look in one direction you see Plum Island and if you look in the other you see Orient Point. I imagine if you take the ferry that leaves from there you might be able to get a view that shows both at the same time, though.

It's been a few years since I was at that particular place on Long Island for the Long Island Lighthouse Challenge. Esther and I volunteered at that point one year for the Challenge.
